Two angle measures of a triangle are 35° and 50° . What is the measure, in degrees, of the other angle?
The measure of the third angle of the triangle is 95°
According to the triangle theorem :
The sum of the angles in a triangle is 180° ; i.e Given a triangle A, B and C ; the sum of it's angles :
A + B + C = 180°
Hence, for a triangle with two of it's sides being ; 35° and 50°
Let the third angle = x
The third angle will be :
180° = (35° + 50° + x)
180° = 85° + x
x = 180° - 85°
x = 95°
Hence, the measure of the third angle is 95°

Sheila in her study partner flipped a coin 120 times they flipped 70 has and 50 tails what is the experimental probability that the next flip will be heads up?
Answer:
7/12 = 0.5833 = 58.33% experimental probability that the next flip will be heads up.
Step-by-step explanation:
Experimental probability:
An experimental probability is given by the number of desired outcomes divided by the number of total outcomes, considering a number of previous trials.
What is the experimental probability that the next flip will be heads up?
120 previous trials.
70 were heads.
So
[tex]p = \frac{70}{120} = \frac{7}{12} = 0.5833[/tex]
7/12 = 0.5833 = 58.33% experimental probability that the next flip will be heads up.

Answer:
this is a wild guess but 10.
Step-by-step explanation:
Not sure if you're allowed to do this but i added the x's
7x+3x= 10x
10x+20.
I then subtracted 10 by both sides. That leaves me with 10.
x =10

the difference of two numbers is 7. Three times the greater number is 72. find the numbers
Answer:
[tex]\huge\boxed{\tt{x = 24, y = 17}}[/tex]
Step-by-step explanation:
Let the greater number be x and the smaller number be y.
So,
Condition # 1:
x - y = 7 --------------(1)
Condition # 2:
3x = 72 --------------(2)
Taking Eq. (2)
3x = 72
Divide both sides by 3
x = 72 / 3
x = 24
Now, Put x = 24 in Eq. (1)
24 - y = 7
Subtract 24 to both sides
-y = 7 - 24
-y = -17
y = 17

Amy is attending physical therapy after knee surgery. She walked 6 1/4 miles over 3 days. How many miles is this per
day? (Simplify the answer and write it as a mixed number)
Answer:
Step-by-step explanation:
2 1/12 miles per day
The number of miles Amy walked per day is given by the equation
A = 2 1/12 miles
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
The total number of miles walked by Amy = 6 1/4 miles
The total number of miles walked by Amy = 25/4 miles
And , the number of days = 3 days
So , the number of miles per day A = total number of miles walked by Amy / number of days
Substituting the values in the equation , we get
The number of miles per day A = ( 25/4 ) / 3
The number of miles per day A = 25/12
The number of miles per day A = 2 1/12 miles
Hence , the equation is A = 2 1/12 miles
